Posttraumatic stress disorder (PTSD) treatment is often complicated in veterans by co-occurring conditions including pain, insomnia, brain injury, and other mental disorders. Pharmacologic approaches to these conditions can produce an accumulation of sedating medications with potential for safety concerns. ⋯ Important trends in polysedative use among veterans with PTSD illustrate the complexity of treating an intersecting cluster of symptoms managed by sedative medications. As the VA seeks to improve care by focusing on non-pharmacologic options, our findings emphasize the need for a comprehensive approach that encompasses overlapping conditions of relevance to veterans with PTSD.

The treatment of chronic pain is still unsatisfactory. Despite the availability of different drugs, most patients with chronic pain do not receive satisfactory pain relief or report side effects. Converging evidence implicates involvement of the immune system in the pathogenesis of different types of nociceptive and neuropathic chronic pain. ⋯ IgG is a promising treatment in several chronic pain conditions. IgG is a relatively safe therapeutic strategy, with uncommon and mild side effects but high costs. Randomized, controlled trials and predictive tests are needed to better support the use of IgG for refractory chronic pain.

To determine the prevalence of chronic back pain in the general population and to establish an evidence-based subclassification system for chronic back pain based on pain extent. ⋯ Chronic back pain is prevalent and usually involves additional pain areas outside of the back. This challenges the concept of chronic back pain as a distinct entity. To identify patients who are distressed by chronic back pain, a four-class taxonomy based on pain drawings is both feasible and clinically useful.

Peripheral nerve injury can result in the formation of neuroma/nerve entrapment, a persistent peripheral neuropathic pain state which is often refractory to invasive interventions or medications. Therefore, there is a need in the field of pain management to develop innovative noninvasive therapy in treating post-traumatic peripheral neuropathic pain states. A new intervention, transcutaneous magnetic stimulation (tMS), is derived from the use of transcranial magnetic stimulation in which a rapid discharge of electric current is converted into dynamic magnetic flux for modulating neuronal functions. ⋯ tMS offers a noninvasive treatment option for neuroma-related neuropathic pain conditions. Randomized controlled studies are required in further validating the efficacy of this treatment modality. Additional studies are also needed to assess the underlying electrophysiological mechanisms of the observed analgesic benefit.

To identify and categorize anatomical anomalies of the vertebral artery and determine the relationship of these unexpected variations to the site for cervical transforaminal epidural steroid injections (CTESI). ⋯ CTESI have become a mainstay in the treatment algorithm for painful cervical radiculopathy. Described techniques take extreme care to avoid cannulation of the vertebral artery during this procedure. Unexpected deviation of the artery, or an arterial segment, into the posterior neural foramen, the target zone for CTESI, increases the risk of intraarterial cannulation during injection. Accordingly, the practitioner must be aware of variant anatomy of the vertebral artery and take all precautions to avoid potential complications that may arise as a consequence.
